Is there any way to activate a window with White?

Question

Is there a way to activate or bring a window of an external application to the front? The closest I could get was

var application = Application.Attach("SearchApp");
var searchWindow = application.GetWindows()[0];

searchWindow.Focus(DisplayState.Maximized);

but all that does is maximize it in the background if it's not currently active.

Got it working.

    [DllImport("user32.dll", SetLastError = true)]
    internal static extern bool SetForegroundWindow(IntPtr windowHandle);


    public bool SearchTest(string file) {
        try
        {
            // White stuff, not relevant to problem
            //var application = Application.Attach("SearchApp"); 
            //var searchWindow = application.GetWindows()[0];

            Process p = Process.GetProcessesByName("SearchApp")[0];
            SetForegroundWindow(p.MainWindowHandle);
